Kuhlanta iSodium Hydrosulfide: Imvelaphi Nekucondza

Emkhakheni wephethiloli kanye nemakhemikhali, tinchubo tekucolela letifana nekuvubela nge-vacuum kanye nekudzabuka kwe-catalytic kuvame kukhicita emagesi lane-esidi. Lamagesi lane-esidi avame kuba na-85%–95% we-hydrogen sulfide (H2S), 3%-10% wekhabhoni dioxide (CO2), 2%-5% wemagesi laphilako, kanye na-0.5%-3% waletinye tincenye.

Tindzawo tekucolela letincane naletisemkhatsini tivame kulapha lamagesi lane esidi ngekuwamunya ngesisombululo se sodium hydroxide (NaOH) lengu 30%. I NaOH ihlangana ne H2S kwakheka isodiyamu (i-NaHS). Uma iNaHS lokucuketfwe kulesisombululo ifinyelela ku 30%, lesisombululo sihamba ngendlela yekuhlushwa. Ngemuva kwekuphelelwa ngemanti kanye nekugcila, lokucuketfwe yi NaHS kuyakhula kuya ku 70%, bese le NaHS lencibilikile ibese iyasikwa ibe ngemacembe.

Nomakunjalo, njengoba lamagesi lane esidi ane CO2, kungcola lokufana ne sodium carbonate (Na2CO3) kuyakhiwa ngesikhatsi sekwelapha, kunciphisa kuhlanteka kwemkhicito we NaHS.

Ngekwengeta, uma ema flakers lavulekile esigubhu asetjentiswa kusika iNaHS lencibilikile, iNaHS ivame kuhlangana ne oxygen emoyeni, yakha iSodium thiosulfate (Na2S2O3), levame kubola futsi kumatima kuyigcina. Kusika lokuvulekile kuphindze kukhiphe emagesi lacasulako, kungcolisa indzawo yekukhicita.

Chafata lapha kute utfole sicaphuno lesaphulelo se-sodium hydrosulfide, kutawuba netimanga.
